Timing of bowel irrigation could ease life after rectal cancer surgery
NCT ID NCT07696689
First seen Jul 10, 2026 · Last updated Jul 10, 2026
Summary
This study looks at whether starting trans-anal irrigation (a procedure that uses warm water to help empty the bowel) within three months of stoma closure reduces daily bowel movements more than starting later. The trial involves 250 adults who have had rectal cancer surgery and now suffer from low anterior resection syndrome (LARS), which causes frequent, urgent, or uncontrolled bowel movements. Participants are trained to use a device at home and are followed for nine months to track symptoms, quality of life, and satisfaction.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Water-based transanal irrigation system (Peristeen® Plus device)
- What this could lead to
- If early irrigation works better, it could establish a new standard timing for managing bowel symptoms after rectal cancer surgery, improving daily comfort and quality of life.
- What could go wrong
- This is a mid-sized trial comparing two timing strategies, not a new treatment. The benefit may be modest, and individual results vary. The procedure requires daily commitment and may cause discomfort.
